This invention relates to clutches especially adapted for operablyconnecting a rotary driving member and a member to be dr ven. One objectof the invention is to provide a clutching means in which the disenagement is efiected with certainty and sticking avoided. Another objectis to make such a device reversely operablethat is to say operablewhether the driver turns to the right w or left. Other objects can begathered from the following description.

The invention is embodied in the example herein shown and described, thefeatures of novelty being finally claimed.

In the accompanying drawing Figure 1 is a side view of the drivingmember showing the clutching device and driven member thereon partly insection.

Fig. 2 is a view looking toward the right hand side of Fig. 1 with theparts not sectioned.

In the views the character 5 designates a shaft or driving member. Keyedby key 5 on said shaft 5 is a hub 6 carrying two oppositely extendingarms 7, 7 to the extremities of which are pivoted at 8 the bifurcateends of clutch arms 9. These arms 9 each have two clutching faces attheir free ends. Said arms 9 have perforated ears 9 The character 10designates an annularly grooved sleeve splined to and slidable on theshaft 5, said sleeve having diametrically opposite ears 10 Pivotallyconnecting the ears 9 and 10 at opposite sides of the sleeve are links11,11

so that bv sliding the sleeve on the drive shaft 5 the clutch arms arethrown inward or outward in a plane at right angles to the shaftaccording to the direction in whlch the sleeve is moved.

Turning loosely on the hub 6 is the dr ven member which, in the exampleshown, 1s a sprocket wheel 12. The wheel 12 is provided on its face nextthe arms 7, 7 with two substantially diametrically located stout lugs13, 13, that extend into the path of the clutch heads of the arms 9, 9,the hub of the wheel 12 being secured from longitudinal movement on thehub 6 by means of a collar 14 and set screw 15.

The groove 16 of the sleeve 10 is engaged by the ordinary forked arm 17for sliding the sleeve on the drive shaft.

The operation is this: When the shaft 5 is driven and it is desired thatwheel 12 shall remain idle the sleeve 10 is moved away from the wheel 12as shown by broken lines Fig. 1, thus keeping the arms 9 drawn inward inposition where the clutch ends of those arms will pass the lugs 13, 13.Conversely when it is desired to drive the wheel 12 the sleeve 10 ismoved toward the Wheel, as shown by full lines Fig. 1, through the links11, 11 shoving the arms 9 outward and the clutch heads of those armsinto position to engage said lugs and therefore drive the wheel 12. Thewheel 12 can be driven either to the right or the left, according towhether the shaft 5 is driven to the right or left. lVhen driven to theright, as viewed in Fig. 2, the face 18 engages one side of the lug 13and-when driven to the left the face 19 engages the opposite side ofsaid lug, as shown by one of the broken line positions. The other brokenline positions show the arms 9 hav ing their ends withdrawn from pathsto engage the lugs 13 at either side. The engaging face 19 should becurved on an are drawn from a circle having for its axis the pivot 8 andthe face of the lug engaged by the face 19 should be similarly curved.It will be observed therefore that either of these clutch faces can beeasily disengaged from the lugs.

in order to brace and prevent lateral. Wabbling of the arm 9 and holdthe clutching head in operating line the end of the rigid arm 7 isangularly extended as seen at 7 to lie well into the bifurcate pivotedend of said arm 9.

The forms of the parts can be changed without departing from the gist ofthe invention as claimed.

What I claim is:

1. A reversible clutch including a rotary drive member and a drivenmember, a lug on the driven member, and an arm pivoted on an axis atright angles to the plane of the driven member carried by the drivemember swinging in the plane of the arm memher and means sliding on thedrive member linked to said arm to swing the latter into and out of thepath of the lug on the driven member.

2. A clutch including a reversible rotary drive member and a drivenmember, a lug on the driven member and an arm fixed on the drive member,an arm pivoted to said fixed arm to swing in a plane parallel to'theplane of the driven member, a sleeve turning with and sliding on thedrive member, said pivoted arm having jaws to engage opposite sides ofsaid lug, and means linking said pivoted arm to said sliding sleevewhereby said pivoted arm may be moved into or out of position to engagesaid lug for rotation of the driven member at either side of said lugaccording to the direction of rotation of said drive member.
